A geographic coordinate system ( GCS) is a spherical or geodetic coordinate system for measuring and communicating positions directly on Earth as latitude and longitude. [1] It is the simplest, oldest and most widely used of the various spatial reference systems that are in use, and forms the basis for most others.

A geographical coordinate system is a coordinate system. This means that every place can be specified by three sets of three numbers, called coordinates. A full circle can be divided into 360 degrees (or 360°); this was first done by the Babylonians; Ancient Greeks, like Ptolemy later extended the theory. Today, degrees are divided further.
Supports more than 3,000 coordinate systems and 400 datums worldwide. Place pushpins on the map and calculates automatically the coordinates in the selected coordinate system or datum. Perform transformation between coordinate systems and/or datums.
May 21, 2023 · The coordinate system used to define locations on the three-dimensional earth is the geographic coordinate system (GCS), based on a sphere or spheroid. A spheroid (a.k.a. ellipsoid) is simply a slightly wider sphere than it is tall and approximates the actual shape of the earth more closely.
A geographic information system (GIS) consists of integrated computer hardware and software that store, manage, analyze, edit, output, and visualize geographic data. [1] [2] Much of this often happens within a spatial database , however, this is not essential to meet the definition of a GIS. [1]
The World Geodetic System ( WGS) is a standard for use in cartography, geodesy, and navigation including GPS . It comprises a standard coordinate system for the Earth, a standard for raw altitude data, and a geoid that defines the nominal sea level. The latest revision is WGS 84 . Categories: Geocodes. Geodesy.
WikiProject Geographical coordinates aims to better organize location information in articles containing a set of numbers that identifies location on and relative to the Earth.
